Note, since this is a rotate, the patches I proposed in 17886 will generate
much better code for this one case (basically mov/mov/xchgl -- it could be
improved by a peephole to do the moves directly instead of

We only run into the problem with red zone enabled, which is x86-64. We have
2 issues:
1. When prologue uses mov, memory shouldn't be clobbered. But
ix86_expand_prologue calls pro_epilogue_adjust_stack which clobbers
memory.

The change looks reasonable. I will check it out. But I still don't
like pro_epilogue_adjust_stack doesn't tell the truth about if memory is
clobbered. Why not do something like

There is another issue when converting stack additions to pop:
(define_peephole2
[(match_scratch:SI 0 r)
(parallel [(set (reg:SI SP_REG) (plus:SI (reg:SI SP_REG) (const_int 4)))
